Aerial Passenger Device   Wire Rope  Online Real-time Safety Monitoring System

TCK•W® Online Real-time Safety Monitoring Management System for Wire Rope of Aerial Passenger Device

System Introduction

As a high-risk and key component of aerial passenger device, wire rope is regarded as the “lifeline” for the cableway transportation. However, for a long time the rope failure accidents always lurk during the operation of wire ropes due to the lack of scientific and reliable inspection instrumentation. Management departments mostly adopt the methods of visual inspection and periodic replacement of wire ropes to ensure the safety of in-service wire ropes.

However visual inspection only detects external flaws, but cannot detect “major hidden dangers” such as internal broken wires, abrasion, corrosion, fatigue and so on. Periodic replacement of wire ropes results in huge waste which cannot radically prevent wire rope failure accidents.

TCK•W® Weak magnetism inspection technology successfully solves the problems in the safety inspection of aerial cableway wire rope and provides cableway management departments with reliable method to monitor the safety status of wire ropes, avoid rope failure accidents, scientifically reduce the cost of wire rope replacement and enhance the service efficiency of wire ropes.

-Shield-type information receiving & conversion and anti-interference design。

③TCK•W® Photoelectrical Distance/Speed Measuring Device

-Adopt high-precision photoelectrical encoder and light aluminum frame;

-Anti-loosening mechanical structure, self-clamp-floating cantilever support, and friction wheel with multi-channel anti-slip rings;

-Integrate anti-shake, pulse shaping, and equal accuracy tachometer…etc industrial design with features of stable signal and light accuracy meter/speed measuring.

④ TCK•W® Self-controlled Sound And Light Alarm System

-Real-time and graded alarming responses, with “yellow light” for early flaw warning and “red light” for over-limit flaw warning.

-With over-limit flaws, the “red light” will be on and pre-programmed .safety measures will be acted simultaneously.

-High-power on-site sound and light displaying device。

SMS safety report function device

-Based on the real-time monitoring results and historical statistics, the alarm information will be showed and locked in terminal interface. The corresponding alarm information can be remotely sent to manager's mobile phone by SMS according to the system pre-setting.

⑤TCK•W® Multi-channel Terminal Workstation

-Multi-channel step-by-step calling, synchronous and high speed data receiving & sending operation mode, optional configuration for wire/wireless communication.

-Dedicated command and control software, manual/auto switch operation mode.

-Tsimple man-machine interactive mode.

-Compatible with the LAN or public network for information sharing.

-Real-time testing data collecting, analyzing and processing, with file-type data management system.

-Support testing data retrieving and test report printing whenever needed.
